Question

A train travels 60 kilometre in one hour how long will it take to go 150 km with the same speed​

Answer 1

Answer:

First of all, we must assume the training n continues at a constant average speed of 60km/h

Three way I found to approach this problem are below:

Let ‘a’ be the amount f time taken for the train to cover 90km.

1)

Because: 90/60=1.5,

60km/hr=90km/a

60km/hr=90km/1.5

a=1.5

Therefore the time rain will cover 90km in 1.5hrs

2)

60:90=2:3

Therefore:

60*(3/2)=a

a=90minuteS

3)

60km/h=1km/minute

90km*(1km/minute)=90km/90minutes

Answer 2

2.5 hour
